European sales require a $1,000 USD surcharge to facilitate export processing. Units are approved for installation in United States of America registered aircraft under the terms of U.S. Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) SA04230CH and its Approved Models List (AML). The STC Group, LLC does not hold and is not seeking a European Union Aviation Safety Agency (EASA) Supplemental Type Certificate (STC). The units are not certified under Conformité Européenne (CE) standards. Units are installed in aircraft and administratively validated as a basic modification limited to one aircraft serial number. Purchaser for use in a non-U.S. registered aircraft assumes all expenses required by the relevant Civil Aviation Authority with jurisdiction over the aircraft including where applicable, EASA.
